Specification of Ilettei's Patent. g Patented lay 1 913.?

Application filed December}, 1911. Serial No. 663,309;

Chicago, in the county of'Cook and State of Illinois, have invented a certain new and useful Improvement in Friction Draft-Rig. ging for Railway-Cars, of which the following is a full, clear, concise, and exact de scription, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in end sill, 11 the carry iron, 12 the buffer friction draft rigging for railway cars.

One of the objects of my invention is to provide a friction draft rigging that may be; applied to railway cars, having side plates? or stop castings arranged for spring draft gear or tandem spring draft rigging, and

thus provide a friction draft rigging of high I cushioning capacity to be substituted on railway cars for the lower capacitied spring draft rigging without necessitating any; change in, or the removal of the side plates now in use'in spring draft rigging.

Another object is to provide a friction draft rigging which will have a high shock absorbing capacity, and suitable for mounti-ng in the present draft attachments.

Another object is to provide a friction draft rigging which may'employ the said side plates or stop castings now widely used": in tandem spring draft rigging, and thus; be adapted to adequately distrlbute heavy; shocks at different points to the center sills, and to provide a friction shell which may be of simple construction, and provided? with shoulders for engagement with the lim-, iting stops, which shoulders may -be integral with the shell, and also a draft rigging in{ which all the parts of the shock absorbing:

mechanism may beheld in assembled relation as a single structure, and thus fa'cilitate installment and removal and inter-' changeability with a spring draft gear with-' out any change of yoke or carrier plates.

j is attached, prefer My invention consists in the novel con-1' structlon of parts and devices, and in the novel comblnatlon of parts-1md ,devices} objects are practically accomp ished.

herein shown and described b i which These;

part of this specification Figure 1 is an elevation partly in central vertical section online 1, 1 of Fig. 2. Fig. 2 is a plan view partly in horizgntal section on line 2, 2 of Fi -1. Fi Sis a lan'view part1 in horig g P y zontal section showing the osition of the friction draft rigging in full draft. Figs. 4 and 5 are cross sections on lines 4, 4 and 5, 5 respectively of Fig. 1. Fig. 6 is a perspective view of the wedge. Fig. 7 is a perspective 'view of one of the friction shoes. Fig. 8 isa perspective-view of the friction cylinder.

In the drawings 9 represents the draftor 5 center sills or members of the car frame to which the draft rigging is applied, 10 the plate, 13 the draw bar, 14.- the draft yoke, 15 the carrier and tie plateall these parts performing their usual functions and being preferably of standard car construction.

The numeral 16 designates the side plates I mediate stop shoulders 23 and 24. The side plates or stop castings 16 arepreferably also provided with an upper horizontally disposed longitudinal integral guide flange 25 for the adjacent follower members. v

.In preferable construction the main web 26 of the side plates or stop castings 16 is. furnished with transverse right angle inwardly projecting convolutions 27 therein, having'corners slightly rounded to form the main :stops 17 19, 20 and 18, and the intermediate stops 21, 22, 23 and 24, and a series of outwardly projecting right angle convolutions 28 forming the bearing faces 29;

preferably four in number, which are in contact with the center or draft sill 9 of the car to which the side plate or stop casting 16 a 1y by the rivets 30.

The rea-rfollower 31 is within the draft yoke 14, and abuts against the stop shoulder .18 in normal position, and onv rearward movement of the draw bar, and on forward movement of the draw bar abuts against the 1 movement of the draw bar the forward movement of the rear follower is limited by the rear limiting stop 24. 32 is the front folthe follower 32 is limited by' the front front stop shoulders 17, and on rearward movement of the draw bar'the movement of inter mediate limiting stop shoulders 21.

The friction. shell? is mounted between the draft sills 9 Within the "draft yoke 14:, and intermediate the front and rear followers 32 and 31respectively. The said fricti' n'shell is of cylindrical form-or circular:

intermediate its ends of, though preferably in cross section, and is exteriorly provided, w th a multiplicity with two transverse.

' preferably integral, shoulders '"3.4.. and 35, 34'

The'said shoulders 34 and to fit between the upper and lower strap so being the forward and 35 the rear shoulder," 16v each preferably Substantially rectangular in form, and

lower portions of the cylinshell by suitable means, pref-' erably the ribs 36, longitudinal of the cvl the cylindric portion of thefriction shell and with the shoulders 34 and 35, and of a. suitable number with intervening grooves 37. The said shoulders at their verticalv edges are each preferably transversely hollow, as illustrated in Fig. 8 at points 38. 35 are adaptedof the draft yoke 14, and the sides of the, same are spaced apart so that the forward shoulder when the gear is at rest or in biifling movement of the same abuts against the middle stop shoulderslQ of. the side plates 16,.a nd the rear shoulder abuts, I against the rear intermediate stop shoulders 23, a nd'on forward movement of the draw 1 jinyand which is in sliding contact with the i bar, as in pulling, the forward shoulder -n1ovestoward, and upon full draftabuts against the front intermediatelimiting stop shoulder-Q2, and the rear. shoulder moves toward, and upon full draft abuts againsti I t the middle stop shoulder 20.

' The friction shell 33 has cylindriefriction face 39 extending longitudinally thereexterior faces 41-0 of thesegmental friction shoes 41', which are preferably three in num- *z'ber. Each of the said friction shoes has a '50" for the antiefriction. roller 44, one of wedginginner face42 and a stop shoulder which is placed. between each of the vfriction shoes and the corresponding wedgeface of the wedgeeti, which is placed between the frontfollo wer 32 and the frictionshoes 4:1. The said friction shoes ell are provided each with segmental shoulders 47 against whichthe front end of'the springd-S rests.

The cylinder 83 is preferably provided at either side between the transverse, preferably integral shoulders 34 and 35, with openings or slots 56, thus permitting the use of springs of large diameter without enicroachi-ng upon the oppositely arranged, middle stop shoulders 19 and 20. r
